The improved inter-integrated circuit (I3C)
A new successor to the Inter-Integrated Circuit (I2C or I2C) bus communication interface is under development, hosted by the Sensor Working Group at the MIPI Alliance. The Improved Inter-Integrated Circuit, I3C, (pronounced “Eye-three-See”) is backward compatible with I2C but will be better suited for handling an abundance of sensors. The I3C specification was released in […]
Teardown: Inside Sphero’s R2-D2 toy
Our teardown of R2-D2 shows what’s inside this little droid with a big personality. One of the hot new toys released in advance of the new Star Wars movie is R2-D2 by Sphero, the same toymaker that developed the BB8 for the 2015 Star Wars sequel called The Force Awakens. As with the BB8, R2 […]
Magnetic Reed switch: an amazing addition to your design toolbox
Reed switches are simple, passive, electromechanical components that were invented circa the 1940s. Reed switches aren’t mentioned much in electronic literature or forums that much, but they have some amazing capabilities. Reed switches are sometimes called magnetic switches. Reed switches open or close when exposed to a magnetic field. The reed switch consists of a […]

Driving high-wattage output with a solid-state relay
Microcontrollers are designed to handle only low voltage and current signals on their input and outputs. So how does one control and drive a high wattage load such as an electric heater using an MCU? One of the easiest and most efficient ways is to use a Solid-State Relay (SSR). An SSR allows you to […]
Microcontrollers vs. Microprocessors: What’s the difference?
Microcontrollers (MCUs) tend to be less expensive than, simpler to set-up, and simpler to operate than microprocessors (MPUs). An MCU can be viewed as a single-chip computer, whereas an MPU has surrounding chips that support various functions like memory, interfaces, and I/O. The MCU vs. MPU question may seem simple, but there are some prominent […]
Gallery: Neat tech on display at ADAS & Autonomous Vehicles USA
A focused forum on the here-and-now of self-driving technology held in Novi, Mich., staged by TU-Automotive, featured presentations by Tier 1 suppliers, researchers, and automakers. Also, there were a few displays of interesting technology. Here are a few examples of what was there to be seen. NEXT PAGE: A washer system for car cameras
